Bandcamp is US owned, but still worth mentioning I think because of their commitment to high revenue sharing, about 80-82% goes directly to the artists. They have custom playlists, and offer high quality formats as well.
If the goal is a quality product and an ethical approach to supporting artists I'm not dead set on only using European alternatives
Yeah, I remember the last one having something like 25 parties and in the area of 400 candidates
Edit: I checked. It was 26 parties with 955 candidates!
